The Panthers have delivered their second offseason stunner in as many years, firing general manager Dave Gettleman on Monday after four seasons.

Gettleman, 66, worked in the Giants' front office from 1999-2012 before being hired as Carolina's general manager prior to the 2013 season. He made the playoffs in three of his four years, including a trip to the Super Bowl in 2015.

"After much thought and a long evaluation of our football operations, I have decided to relieve Dave Gettleman of his duties as general manager," Panthers owner Jerry Richardson said in a release announcing the decision. "I want to thank Dave for the role he played in our success over the past four seasons. While the timing of this decision is not ideal, a change is needed."

Gettleman served as the Giants' pro personnel director from 1999-2011 and was their senior pro personnel analyst in 2012. He was a contender for the Giants' GM job when Ernie Accorsi retired, but the position ultimately went to Jerry Reese, who still holds it.

Gettleman built the Panthers roster that finished 15-1 in 2015 and appeared in Super Bowl 50, where they fell to the Broncos. But Carolina slipped to 6-10 last year after a tumultuous offseason that saw Gettleman rescind cornerback Josh Norman's franchise tag after negotiations turned sour. Norman then became a free agent and signed with the Redskins.

The Panthers are now dealing with a potential mess involving Pro Bowl tight end Greg Olsen, a former Wayne Hills High star. Olsen wants a new contract and has suggested he will hold out from training camp if he does not receive one.
